Front

What are lines that cross over each other at one point called?

Back

Intersecting Lines

Front

What is the solution to the system of equations represented by the point (4, -1)?

Back

(4, -1)

Front

What is the slope-intercept form of the equation -8x + 2y = 4?

Back

y = 4x + 2

Front

What does it mean if a system of equations has infinitely many solutions?

Back

The equations represent the same line.

Front

What is the solution to the system of equations represented by the point (3, 0)?

Back

(3, 0)

Front

What are parallel lines?

Back

Lines that never intersect and have the same slope.

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1)

Front

What is the graphical representation of a system of linear equations?

Back

The point(s) where the lines intersect represent the solution(s).

Front

What does it mean if two lines are coincident?

Back

They lie on top of each other and have infinitely many solutions.

Front

What is the y-intercept of the line represented by the equation y = 2x + 3?

Back

The y-intercept is 3.
